Se trata de un vidrio sodoc\u00e1lcico y de la arcilla caol\u00edn, que contienen nanopart\u00edculas capaces de reducir la infectividad viral m\u00e1s del 99% en 10 minutos de contacto.\u00a0Un estudio de investigadores espa\u00f1oles ha identificado un tipo de vidrio y una arcilla que tienen una potente actividad viricida. Se trata de materiales inorg\u00e1nicos de bajo coste que pueden servir para descontaminar superficies, l\u00edquidos y aires que contengan part\u00edculas virales. Estos dos materiales reducen la infectividad viral m\u00e1s del 99% en 10 minutos de contacto y han sido probados con los virus de la covid-19, de la gripe, del herpes simple y con adenovirus. Tambi\u00e9n son eficaces contra bacterias y hongos. Estos materiales podr\u00edan ser utilizados como eficaces desinfectantes antivirales y en el futuro podr\u00edan servir para desarrollar medicamentos antivirales con baja o nula toxicidad.<\/p>\n
Inorganic materials can provide a set of tools to decontaminate solid, liquid or air containing viral particles. The use of\u00a0disinfectants<\/a>\u00a0can be limited or not practical in scenarios where continuous cleaning is not feasible. Physicochemical differences between viruses raise the need for effective formulations for all kind of viruses. In the present work we describe two types of antimicrobial inorganic materials: i) a novel soda-lime glass (G3), and ii) kaolin containing\u00a0metals nanoparticles<\/a>\u00a0(Ag or CuO), as materials to disable\u00a0virus infectivity<\/a>. Strong\u00a0antiviral properties<\/a>\u00a0can be observed in G3 glass, and kaolin-containing nanoparticle materials showing a reduction of viral infectivity close to 99% in the first 10\u00a0\u200bmin of contact of vesicular stomatitis virus (VSV). A potent virucidal activity is also present in G3 and kaolin containing Ag or CuO nanoparticles against all kinds of viruses tested, reducing more than 99% the amount of HSV-1,\u00a0Adenovirus<\/a>, VSV, Influenza virus and SARS-CoV-2 exposed to them. Virucidal properties could be explained by a direct interaction of materials with viruses as well as inactivation by the presence of virucidal elements in the material lixiviates. Kaolin-based materials guarantee a controlled release of active nanoparticles with antiviral activity. Current\u00a0coronavirus<\/a>\u00a0crisis highlights the need for new strategies to remove viruses from contaminated areas. We propose these low-cost inorganic materials as useful disinfecting antivirals in the actual or future pandemic threats.<\/p>\n
